The importance of a strong manufacturing sector for structural transformation

Except for a handful of small countries that benefited from natural-resource bonanzas, all of the successful economies of the last six decades owe their growth to rapid industrialization. If there is one thing that everyone agrees on about the East Asian recipe, it is that Japan, South Korea, Singapore, Taiwan, and of course China all were exceptionally good at moving their labor from the countryside (or informal activities) to organized manufacturing. Earlier cases of successful economic catch-up, such as the US or Germany, were no different.

Manufacturing enables rapid catch-up because it is relatively easy to copy and implement foreign production technologies, even in poor countries that suffer from multiple disadvantages. Remarkably, my research shows that manufacturing industries tend to close the gap with the technology frontier at the rate of about 3% per year regardless of policies, institutions, or geography. Consequently, countries that are able to transform farmers into factory workers reap a huge growth bonus.

To be sure, some modern service activities are capable of productivity convergence as well. But most high-productivity services require a wide array of skills and institutional capabilities that developing economies accumulate only gradually. A poor country can easily compete with Sweden in a wide range of manufactures; but it takes many decades, if not centuries, to catch up with Sweden’s institutions.

Consider India, which demonstrates the limitations of relying on services rather than industry in the early stages of development. The country has developed remarkable strengths in IT services, such as software and call centers. But the bulk of the Indian labor force lacks the skills and education to be absorbed into such sectors. In East Asia, unskilled workers were put to work in urban factories, making several times what they earned in the countryside. In India, they remain on the land or move to petty services where their productivity is not much higher.

Important message: A meaning structural transformation would require “an industrialization drive, accompanied by the steady accumulation of human capital and institutional capabilities to sustain services-driven growth once industrialization reaches its limits.”

Cautionary note:

But this time-tested recipe has become a lot less effective these days, owing to changes in manufacturing technologies and the global context. First, technological advances have rendered manufacturing much more skill- and capital-intensive than it was in the past, even at the low-quality end of the spectrum. As a result, the capacity of manufacturing to absorb labor has become much more limited. It will be impossible for the next generation of industrializing countries to move 25% or more of their workforce into manufacturing, as East Asian economies did.

Manufacturing industries will remain poor countries’ “escalator industries,” but the escalator will neither move as rapidly, nor go as high. Growth will need to rely to a much greater extent on sustained improvements in human capital, institutions, and governance. And that means that growth will remain slow and difficult at best.
